Hi I am new to the forum, and have just got hold of a Kobo Arc. Whilst everything looks good, I have connected the Kobo to my PC to upload my EPUB books from file, on connecting the Arc I have noticed that the onboard memory of the Arc is depicted/displayed as having 4.8GB free of 5.4GB. I am confused as I have got the 16GB Arc version and cannot therefore understand why the Arc is only showing a total of 5.4GB. Can anyone help me please?
